" Fundamental philosophic ideas are almost always profoundly controversial. They are not bromides; they are not self-evident, unless it’s like “A is A.” They involve tremendous abstraction and tremendous complexity. And therefore, if you find that you can zip them off in one or two sentences that absolutely no one could ever question, the chances are very strong that you did something wrong, that you missed out on what this idea actually says.
